Re: [PHP-DB] Remote DB Connection: Pros and Cons?
Thank you all for the responses. I think we're going to try replicating the
databases with Slony. Wish me luck!

No need to create something that has already been done.
Use slony or something to replicate the database.
Any updates the website does (like an event registration or profile update)
would be done remotely to the office db. In this scheme the website db would
be 10 minutes behind. We can live with that.
When you do a registration, get it to use a remote database connection
instead of the 'local' one.
$local_connection = pg_connect('localhost');
$remote_connection = pg_connect('remote_server_ip');
$remote_result = pg_query($remote_connection, $query);
Doing everything by remote connection would be easier, but we're worried
about the performance.
The only way to find out would be to test it really. As long as you have
a decent connection in to the office and a decent connection on the
remote end and aren't pulling through a ridiculous amount of data in
queries (eg pulling through 50,000 records when you only really need
10), you should be fine.

Re: [PHP-DB] Remote DB Connection: Pros and Cons?
Hi You would be better off with the database server and php on the same server - both sites. You will find there is significant lag if there is a poor connection between the web and database server, but if you are just accessing web pages and updating data, even with large pages there is not much delay. You could always try both permutations and see, but that has been my experience.

RE: [PHP-DB] Remote DB Connection: Pros and Cons?
What about setting up replication between the servers? Make the the web a slave of the office one and make it read only so avoid messing up the data. bastien Date: Thu, 11 Oct 2007 18:08:29 -0600 From: [EMAIL PROTECTED] To: php-db@lists.php.net Subject: Re: [PHP-DB] Remote DB Connection: Pros and Cons?

RE: [PHP-DB] Remote DB Connection: Pros and Cons?
Have any of you tried running a PHP website using a remote database
connection?
Yes. If you mean the web server is on 1 box and the database server is on a
2nd box.
We currently have an in-house PHP website driven by a PostgreSQL database
that is HEAVILY administered within the office with an administration sister
site (also PHP).
We have our database servers within our medium sized company and internal web
servers as well as a hosting company hosting external web servers.
All access at least 1 of our internal database servers.
We wouldn't want the 3rd party host to actually have our database {although
remote replication is (re)considered once in a while}.
Problem: the office connection is having trouble keeping up with the website
traffic. Our IT guys want to outsource the whole server to a co-location
facility, but the administrators don't want the extra lag on the admin site.
Is it feasible to host the database and admin site in the office, but
outsource the website and connect to the office database remotely? Is there
any other way to do this?
Tony
Missed that before I hit reply. This _IS_ what we do.
Cons:
Some stranger at the 3rd party hosting site (or someone hacked into your remote
web server) could see the passwords used to connect to your internal database.
The connection between the remote web server and local database is still a
performance/connectivity issue.
Fun with firewall rules.
